Modern software is rarely built from scratch; most applications rely heavily on open-source libraries, third-party APIs, and external components. While this accelerates innovation, it also introduces hidden vulnerabilities. When a flaw appears in a widely used component, thousands of organisations can be exposed overnight.
To combat this, gaining comprehensive software supply chain visibility is essential for organisations to reduce third-party risk and strengthen cyber resilience.
Why Software Supply Chain Security Matters
Software supply chain attacks have become a major enterprise risk as attackers increasingly target shared libraries. Managing the inherent open-source dependency risk is difficult because third-party dependencies often result in limited visibility into component versions and delayed patching. Without clear insight, security teams struggle to understand their exposure during emerging threats.
What Is an SBOM?
A Software Bill of Materials (SBOM) is a detailed inventory of all components used to build an application, including open-source libraries and third-party packages. Think of an SBOM as the foundation of software supply chain visibility; it acts as an ingredient list that allows organisations to know exactly what is inside their applications and where risks may exist.
Key Benefits of Implementing SBOMs
Implementing SBOMs delivers several practical advantages for organisations looking to strengthen software supply chain security.
Key benefits include:
1. Improved vulnerability management
A primary benefit is improved SBOM vulnerability management, which provides instant visibility into components, allowing teams to quickly identify exposure and prioritise remediation based on real-world risk.
2. Faster incident response
During a security incident, time is critical. SBOMs allow responders to immediately determine which systems rely on vulnerable or compromised components, reducing investigation time and enabling faster containment and recovery.
3. Stronger third-party risk management
Modern applications depend heavily on open-source and vendor libraries. SBOMs provide visibility into where third-party components are used, helping organisations make informed procurement decisions and maintain stronger supply-chain oversight.
4. Increased security automation
SBOM data can be integrated into vulnerability management and security tools to enable continuous monitoring, automated alerts, and more efficient workflows—reducing manual effort and improving consistency.
How Organisations Use SBOMs in Practice
Real-world use cases highlight how organisations apply SBOMs to strengthen software supply chain visibility:
| Use Cases | How SBOMs Help | Business Impact |
| Responding to newly disclosed vulnerabilities | Quickly identify where vulnerable components exist across applications and prioritise remediation without manual investigation. | Faster patching, reduced exposure window, and lower breach risk. |
| Incident response and investigation | Provide visibility into affected systems and software dependencies during a security incident. | Shorter investigation time and faster containment of threats. |
| Third-party and vendor risk management | Reveal external components used in applications and support risk-based vendor decisions. | Reduced supply-chain risk and better procurement oversight. |
| Compliance and audit readiness | Offer evidence of software transparency and security practices for regulators and customers. | Easier audits, stronger trust, and improved regulatory alignment. |
| DevSecOps collaboration | Create a shared inventory of software components for development, security, and operations teams. | Better prioritisation, reduced friction, and stronger security integration. |
Challenges When Implementing SBOMs
Despite their value, organisations face barriers such as limited visibility across development pipelines and the difficulty of managing legacy applications. Furthermore, sophisticated transitive dependency tracking, identifying the “dependencies of dependencies”, can be complex without automated tools. Many also struggle to maintain accuracy as frequent updates make static inventories outdated.
- Limited visibility across development pipelines: Multiple teams and tools make it difficult to generate consistent, standardised SBOMs without automation.
- Managing legacy applications: Older systems often lack documentation or modern build processes, making SBOM creation more time-consuming.
- Integrating SBOMs into security operations: Many struggle to connect SBOM data with vulnerability management and threat detection workflows.
- Maintaining accuracy over time: Frequent software updates can quickly make SBOMs outdated without automated updates.
- Establishing ownership and governance: Lack of clear roles and policies can slow adoption across development, security, and compliance teams.
Best Practices for Successful SBOM Implementation
To maximise the value of SBOMs, organisations should integrate them into development, security, and governance processes from the start.
1. Automate SBOM generation
Integrate SBOM creation into CI/CD pipelines so every build and release automatically produces an up-to-date component inventory. Automation ensures consistency across teams, reduces manual effort, and keeps SBOMs aligned with rapid development cycles.
2. Integrate SBOMs with security tools
Connect SBOM data with vulnerability scanners, SIEM, and threat detection platforms. This enables continuous monitoring for newly disclosed vulnerabilities and helps security teams respond quickly when risks emerge.
3. Establish governance and policies
Define clear policies for dependency management, patching timelines, and risk acceptance. Strong governance ensures SBOMs remain accurate, regularly updated, and actively used across development and security teams.
4. Leverage cyber risk intelligence
Combine SBOM data with threat intelligence to identify which vulnerabilities are actively exploited. This helps teams prioritise remediation based on real-world risk instead of theoretical exposure.
Strengthening Software Supply Chain Security
Visibility alone is not enough, but achieving software supply chain visibility is the first step toward a resilient development environment. By combining SBOM adoption with cyber risk intelligence and automated response, organisations can proactively reduce third-party risk.
